When load .php file some div goes display: none

When load .php file some div goes display: none

I am using trying to load a .php file via jquery .load or ajax call. I have also tried many other possible
methods to load a .php file vial jquery but I have the same problem.

The problem is that: When I load a php file from jquery 2 divs are unexpectedly goes display: none.

 You can access the website in:   http://filmsfolder.com/noteslib-old/test/notesnew/#/login 
    You can use username:  ahq_balti@yahoo.com  and password:  12345 to see the situation.
     Well, personal details are already in the section-content and is fine. But if you click on
  Activities, Documents for sell etc you can see that the contents inside section-contents are goes
display:none and I have to make them .show via Jquery. 
    In addition, when you are logged in and you are in the browse section and choose sort by: date,rate etc
the Profile section goes display:none unexpectedly.
    I will really appreciate if you take a look in the website and if would like to see the code I will send it to you.
The jquery and ajax calls contents can be found in the end of the index.html.

Thanks.
